2005. Covers sport climbs in the upper half of Boulder Canyon above Boulder Falls, from the Bowling Alley to the Sport Park. A few trad climbs are also included. Topos and written route descriptions. Covers new routes on crags at the Sport Park and elsewhere; has more than 500 routes, including 140 routes not documented in any other guidebook.

The topos are not very artistic, but they are good enough. The bolt counts on routes are pretty accurate.

Unfortunately, the book is incomplete, ignoring several crags developed by Richard Rossiter since 1998. Absent from the book are Sleeping Beauty, Solaris, and Wizard Rock, all with excellent sport climbing. MountainProject.com and Rossiter’s boulderclimbs.com are your best references to these areas. Also missing are new sport routes developed in 2005 on Avalon, Trout Rock, Broken Rock, the Overlook, Myth Rock, and others. MountainProject.com is your only reference for these routes.
